I just want to install a MySQL server to support euck korean charset.
Here is a short how to configure it.
Login into your server as root

Compile MySQL

#cd /root/mysql-5.0.88
#./configure --prefix=/usr/local/mysql --with-extra-charsets=complex
#make && make install

Edit my.cnf

#cp /usr/local/mysql/share/mysql/my-small.cnf /usr/local/mysql/my.cnf
#vi /usr/local/mysql/my.cnf

#add few lines below  :

[client]
default-character-set = euckr

[mysqld]
character-set-client-handshake=FALSE
init_connect="SET collation_connection = euckr_korean_ci"
init_connect="SET NAMES euckr"
default-character-set = euckr
character-set-server = euckr
collation-server = euckr_korean_ci

[mysqldump]
default-character-set = euckr

[mysql]
default-character-set = euckr

# leave other mysql setting as default
# save this files

Restart MySQL

#/usr/local/mysql/bin/mysqladmin shutdown
#/usr/local/bin/mysqld_safe --user=mysql &
